The AirTAC GFR400C15MLJF2K AirTAC Filter Regulator PT1/2 Low-Pressure is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has See datasheet ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The GFR400C15MLJF2K is an AirTAC GFR400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is the size 400 unit with a 1/2 in PT port, the low-pressure regulator type, a manual drain on the bowl, the standard 40 um filter element, an embedded square gauge reading in psi, and a reverse (check) valve fitted. It is supplied without a mounting bracket; a bracket is available as an option. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and the size 400 bowl is polycarbonate (PC).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and catalogue options include a 5 um element (code W), automatic or differential-pressure draining, G (BSPP) or NPT threads, alternative gauge scales in MPa or bar, and an external round gauge. Because AirTAC publishes flow only as curves rather than a single rated figure, we confirm flow and other datasheet figures for your application on request.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Conditioning and regulating air for pneumatic clamps and low-pressure actuators on a stamping line, with the fitted reverse valve blocking backflow through the unit and the psi gauge letting maintenance check set pressure at a glance.
Filtering and regulating air to the tape heads and flap folders on a packaging conveyor, where the manual drain fits a shift-start blowdown routine and the 40 um element keeps debris out of the sealing cylinders.
Supplying clean, regulated air to actuated butterfly and knife-gate valves across a treatment process, with the low-pressure regulator type matching modest set pressures and the manual drain suiting a weekly walkthrough.
Size and port step up with required flow: 200, 300, 400 and 600 carry progressively larger ports, and this unit takes the 1/2 in PT port (G and NPT threads are order options). Choose the drain to match service: this unit has a manual drain, which suits supervised installations where an operator bleeds the bowl on a routine; automatic and differential-pressure draining are catalogue alternatives. The standard element is 40 um; specify code W for the 5 um grade where downstream equipment needs finer filtration. The embedded square gauge on this unit reads in psi, with MPa and bar scales and an external round gauge available. This is the low-pressure regulator type - its exact adjustment range is not published in the catalogue, so ask us to confirm it against your set pressure. Flow is published as curves, not a single rating, so send us your application and we will confirm sizing before you order.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as curves rather than a single rated figure, so we do not quote a rated flow number. Send us your application details and we will confirm the flow figures from the datasheet on request.
The M in the code specifies a manual drain, so condensate is released by operating the drain by hand - a good fit for supervised installations. Automatic (code A) and differential-pressure (blank) drains are catalogue options on the GFR400 if you prefer unattended draining.
